To @ZZ whom it may concern.-

Be it known that LOTTO MErNsHAUsEN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful lmprovement in Liquid-Cooling Apparatus, ofwhich the following is a specification.

My invention relates to liquid-cooling apparatus in which the liquid tobecooled is caused to'flow an extended course through a conduit in onedirection, the said conduit being surrounded by or surrounding a secondconduit, through which a cooling fluid is caused to flow.

While my invention may be employed for cooling any kind of liquid, it isintended more especially for use as a beer or wort cooler.

My object is to provide apparatus of improved construction in which theliquid to be cooled travels an extended course in one directio under thechilling infiuence of a cooling iuid flowing in the opposite direction,the apparatus being particularly compact and effective in operation andat the same time easy to clean.

In thev drawings, Figure l is a broken end view in the nature of adiagram of wort-cooling apparatus of my improved construction; Fig. 2,au enlarged broken longitudinal section taken 'on line 2 of Fig. l andshowing one of the series of cooling devices;v and Figs. 3 and 4,sections taken, respectively, on lines 3 and 4 of Fig. 2.

A A are cooling devices, all of which are constructed as shown in detailin Figs. 2, 3, and 4. Each device A is formed with an outer shellcomprising a central cylinder t, end cylinders sr, and heads q p. In.the head p is a cleaning-opening p', over which ts a cap-plate p2, heldin place by a flanged ring p3, rendering the opening gas-tight. Fittingbetween the cylinders fr t is a diaphragm fn., having a circumferentialflange W, at which it is secured between anges on the said cylinders.The diaphragm n is formed with a central tubular extension n2, having anend n3, provided with a comparatively large central opening n4,surrounded by a series of smaller openings W5. AOn opposite sides of thetubular portion 'n2 and formed integral with the diaphragm are .passagesn, extending from the flanged face of the diaphragm nearly to theopposite end of the space surrounded bythe tubular extension n2. Theflange n within the cylinder is provided on opposite sides of thepassages n@ with a series of openings m7. yExtending through astuffing-box qrin the head q is a pipe m, rendered flaring on the innerside of the cylinder and there provided with an outer circumferentialshoulder m and an end plate m2, which latter is provided with a seriesof openings corresponding with the openings n4 a5 in the diaphragm fn.In the cylinder is a sleeve Z, provided at one end with a ange Z', atwhich it is fastened between adjacent flanges on the shell-sections Z s.At its opposite end the sleeve Z fits tightly over the annular. shoulderm of the pipe m. one end in the tubular section ft2 and at its oppositeend passes through the sleeve Zand fits over the shoulder m, all thejoints being tight. Within the inner cylinder is a central pipe lo',surrounded bya series of smaller pipes k2. The pipe Zt at one end isfastened in the opening n4 of the diaphragm and at its opposite end isfastened in the corresponding opening in the plate fm2. The pipes 7a2are fastened at one end in the openings n.5 of the diaphragm and attheir opposite ends in the corresponding openings in the plate fm2.Between the innercylinder Za and outer shell is a series of pipes t,fastened at one end in the openings a7 in the flange n' and fastened attheir opposite ends in corresponding openings Z2 in the iiange Z.

Extending into the shell-section t is a pipe or conduit B. B is a pipeor conduit extending through the shell-section s and into the cylinderZo, thus communicating with the interior of the latter. C is a pipe orconduit extending through the shell-section s only. The interior of theshell, it will be understood, is separated by the internal walls intochambers or compartments .fr as y y. The chamber .fr surrounds the innercylinder, and the chamber x surrounds the pipes Zo k2 in the innercylinder. The said two chambers communicate through the passages n. Thechambers y 'y' are at opposite end portions of the shell and communicatewith each other through the pipes e'.

The wort or beer to be cooled enters through the pipe m and passesthrough the pipes Zo k2 An inner cylinder 7c fits at IOO to what I termthe primary end chamber y. From the chambery it passes through the pipest' to what I term the secondary end chamber y, whence it escapes throughthe pipe C. The cooling iluid enters at B, iilling the chamber it,surrounding the inner cylinder, and enveloping the pipes i. From thechamber x the cooling fluid iows through the passages a6 to the chamberfr', where it envelops the pipes lo 7a2, escaping through the pipe B.The wort or beer as it enters the device is acted upon by the coolingliquid just escaping from the device, and as it flows to the outlet Cthe wort or beer is subjected to the cooling influence of the coolingHuid which has just entered the device.

Tort or beer to produce the best results in the iinal product should becooled more or less gradually and should not be subjected to a toosudden chilling. For this reason, and also to obtain the best resultsfrom the cooling fluid, it is advisable to cause the beer or wort to beacted upon at first by the cooling iuid after the latter has absorbedheat and iinally by the cooling` iluid at its lowest temperature.

My aim in devising the present device has been to render it as compactas possible and at the same time cause the beer or wort to pursue thelongest possible course under the influence of the cooling Huid, at thesame time permitting the device to be readily cleaned when desired.

Then it is desired to clean the device, the plate p2 should be removedto permit a suitable pipe-cleaner to be passed back and forth throughthe pipes k', 7a2, and i. The chamber @j may be readily cleaned at thesame time and the chamber fg may be flushed out or scrubbed, in whichlatter event the head q may be removed to give more ready access to thechamber y'.

In Fig. l I have shown my devices coupled together in series below ahop-jack D. The wort enters the first device through a pipe D, passingthence through the pipe C to the next device to the end of the iirst orupper seriesv of devices, from the' last of which it passes downwardthrough a pipe C to the first of a second series of cooling devices A.From and bring the wort down to the desired low temperature. The courseof the wort is such that initially its temperature is iniluenced bywater comparatively warm and finally by ammonia-gas at the lowesttemperature which it is desirable to employ.

Vhile I prefer to construct my improved apparatus in all its details asshown and described, the construction may be modiiied without departingfrom the spirit of my invention as deiined by the claims.

lVhat I claim as new, and desire to secure by Letters Patent, is-

l. In a liquid-cooler, the combination of a shell, an inner cylinder andinner walls forming together primary and secondary end chambers andintermediate and intercomuninicating concentric chambers, a conduit eX-tending into one end of the shell, a series of straight and parallelpipes extending from said conduit through the inner intermediate chamberto the primary end chamber, a series of straight and parallel pipesextending from one end chamber to the other through the outerintermediate chamber, a conduit communicating with the secondary endchamber, and conduits communicating respectively with the inner andouter intermediate chambers, substantially as and for the purpose setforth.

2. In a liquid-cooler, the combination of the outer shell, innercylinder 7o and inner cylinder ends Z u forming together end chambers yy and intermediate concentric chambers fr a conduit m at one end of theshell, pipes k 7a2 extending from said conduit through the chamberm tothe chambery, pipes t' extending between the chambers y y', through thechamber ce, and conduits communicating respectively with the chambers @cand y', all constructed and arranged to operate, substantially asdescribed.
